front wheel shaft for Thule Chariot Corsaire 2 bicycle trailer

thingiverse

The shaft of one front wheel broke off right at one the grooves that take a rubber seal. Try to find the plasic (nylon?) washer to reuse in the assembly. This part has a centered hole for a M8 screw (hex head) of 10cm length with no space left. The PLA core should be tightened to allow free rotation but nothing more. Cut the short end to fit the length of the wheel fork AFTER you added the nylon and metal washer to the upper side. The assembly (bottom up) : Hex-head of the screw -> metal washer (to have a bottom surface) -> wheel fork with narrow end of the core in it -> nylon washer -> metal washer -> upper part of the core -> washer (metal, just big enough to clear the shaft hole) -> lock nut (-> dome nut) This might last until you get a replacement part or beyond with good material.
